Connect your SSD1309 oled display to i2c1 port (you can change it during initialization)
SDA->GPIO2
SCL->GPIO3
GND->GND
VCC->3V3(OUT)
CS-> (NOT CONNECTED)
RES->To any GPIO
DC->GND (I2C Adress will be: 0x3C) or DC->3V3 (I2C Adress will be: 0x3D)
The library needs only two files to run SSD1309.hpp and SSD1309.cpp.
This gives you the ability to display a bitmap or array of pixels.
You need the GFX library to make it easier to create images for your display. (GFX.hpp and GFX.cpp)
logo.hpp is an example showing how to create bitmaps.
fonts.hpp contains one font.
Repo provides an example of how a library can be used.
